Ex 13.2, 6 Curved surface area of a right circular cylinder is 4.4 m2. If the radius of the base of the cylinder is 0.7 m, find its height. [𝐴𝑠𝑠𝑢𝑚𝑒 𝜋= 22/7] Let the height of the circular cylinder be h. Radius (r) of the base of cylinder = 0.7 m Curved Surface Area of cylinder = 2πrh 4.4 m2 = 2πrh 4.4 m2 = (2×22/7×0.7×ℎ) m 44/10 m = (2×22/7×7/10×ℎ) 44 m = (2×22×ℎ) h = 44/(2 × 22) h = 1 m Therefore, the height of the cylinder is 1 m.
